fi Glaimsi' (01. 68-198 1: This invention has general reference toyholders foruse in the-'treatmentof 'yarns or threads in annular package -orzcake formation and, more particularly, relates to holdersadapted to sup-- port a pile of packages or cakes duringdyeing or other treatment with liquids. type referred to; asheretofore. ordinarily constructed; were liable to get'out of'order with resultant development" of imperfections in the dyeing; or" the production of cit-shade sections, in theyarn or thread; due to'imperfect absorp tion of' the dyestuff throughout the cakes. More over, the prior: art holders:required; ,much:timelnloadinga-ndcareful setting-up if the -desirable results wereto be expected.

The fundamental aim of ourpresentinvention' is to overcome the above noteddisadvantages.

provision of a simpleholder which is easily-and quickly loaded and unloaded; and which is so constructed as to facilitate ready penetration of the yarnpack'ages or cakes by the liquids;

Other' objects and attendant advantages of- Fig. 2is a vertical section taken as indicated.

by the; angled arrows 11-11 in Fig, 1.

Fig; 3.. is a broken plan sectiontaken approximately. as indicated" by the arrows IIL-IIII in Fig.1..

Figs; 4' and 5 are perspective views of, two of the component parts of'the holder.

In describing the form of our invention, shown in thegthree'sheets ofdrawings herewith, specific terms will be employed tor the sake of clarity, but it is to be understoodthe scope of said invention is not thereby limited, each such term being intended to embrace allequivalentswhich perform the" same function for" an analagous purpose;

Referring more in detail to the drawings, our multiple cake holder comprises a foot-piece or socket connector 6 which is rigidly mounted on, or integrated to, the dye vat I, said connector having a screw-threaded bore 8 into which the correspondingly threaded lower end 9 of a short tubular axial bOSs I0 of a circular stop plate II Holders of the- This objective is realized in practice as hereinafter more fullydisclosed, through shown in Fig; 4, to best'advantage,

is; engaged. Rising axially from plate II is a vertically directed;- hollow post I2 whereof the upper end-is closedas at I 3' and provided: with, .a; central. screw-threaded stud-projection I4;

ThEfhOIIOWIDOSt' I2', it-is,to be seen from Fig, 2, is preferalzily": integrated at its, lower end to the. plate.v I I by a, surrounding weld, I5, and is provided with: groups. of annularly arranged holes I6 centered inzonesspacedby a distance'substantia-lly equal to the thickness of the yarn packages, and with rings of perforations I'I' above and; belcwthe holes I I 6.; The post" I 2; is furthermoreproyi'ded with-;..dlam etrically opposedlongitudinal1 rooves; I 8 having lateral offsets- I 9 1 and; 2Il likewise: spaced; by" a' distance substantially equal to the thickness of theyarnpackages, saidgroovesl 8 beingopenatthe top, see Figs. 2 and,5.

For placement between-packages, we have provided separatorsdesignated 2|, one of'which is Each such separator consists of two components 22,- 22 which are-arranged'back to back and preferably integrated by an outer surrounding weld 23. Obviously an inner: similar weld may likewise be utilized, if desired; Each component 22, 22 is fashioned from:.s heet1- material, such as-metal or adurable plastic; and. appropriately shaped to include a flat annular part-.24 with a peripheral flange orrim 25 and-aninner concentric roundmerged hub 26 witha ring ofholes 21. Particular attention is: directed: to the formation on, the uppercomponent22 ofyeach separator of a pair of diametrically-opposed indentations or lugs 28, Figs; 2 and 4; functional to enter thegrooves I8 in the post. Upon placement of a separator over a package and impartation of a slight turn thereto, the indentations 28 enter the related groove ofiset I9, or" 20 to lock the separator to the post I2.

Seated on and integrated'to the circular stop plate, I I by aweld as .at 29,, is an element 22' likethelower. component. of one of the separae tors 2I., said element. having in its hub, a. ring of holes;2'!.- for registry-with thelowermost ring ofgholeszfl in;the-ho1low-post I2 It is'also to be notedthat-we.havetprovided a cover element 22b for the uppermost package-in thepilewhich element is, also like-oneoi theicomponents of: a separator, and which is integrated by a, weld 29 to a plate 30 in turn similar to the stop plate II, said plate 30 being provided with a central aperture 3| to engage over the stud projection I 4 at the top of the post. After placement, plate 30 with the attached element 22b is secured by a clamp nut 32 screwed onto the projection I4 at the top of post l2.

After common practice in the art, the thread in the package is protected within a fabric wrapper. In the use of the holder, an initial cake or package 33 is impaled over the post I2 and lowered until it seats upon the element 221:. attached to stop plate I], as shown in Figs. 1 and 2. A separator 2! is then applied to the top of the post 12, with incidental entry of its diametral lugs 28 into the longitudinal grooves I8, and then slid downwards onto the package when said indentations will register with the lateral groove offsets 20. Then, by impartation of a slight turn to the separator 2|, the lugs 28 thereof are engaged in the respective groove offsets 20 and said separator thereby locked in position. Other cakes and separators are then applied in a similar manner until the holder is filled,-

and finally the cover plate 39 is placed over the last cake and secured by the nut 32 as in Fig. 2. In the assembled organization, it will be observed that the peripheral flanges of the separators 2| and of the stop and cover elements 22a circumferentially lap the packages, and that their hubs 22b engage partway into the axial hollows of the cake, with the holes in said hubs registering substantially with the rings of I! and IT in post l2. As a consequence, and by reason of the illustrated allocation of the grouped rings of holes IS in the post, the treating liquid is free to flow through and around all of the packages or cakes in the pile so that uniform and thorough penetration of the threads or yarns is assured, while said packages or cakes are efiectively held against displacement.

Having thus described our invention, we claim:

1. In a holder for supporting a pile of annular yarn packages or the like, a cylindric post upon which the packages are adapted to be impaled, said post having a longitudinal groove in its outer surface with lateral offsets spaced by a distance corresponding substantially to the thickness of a yarn package; discoid stop element for the first applied package affixed to the post at the bottom; aXially-apertured discoid separators for impalement upon the post between packages, each separator having an inwardly projecting radial lug fitting the groove in the post and adapted, when the separator is partially rotated after application over ayarn package, to lock into one of the olfsets of said groove; 2. discoid cover element for engaging downward over the topmost package in the pile; and means for removably securing the cover element to the post.

2. A support for multiple annular yarn packages or the like characterized as in claim l, wherein each separator is provided with oppositely-directed circumferential flanges to peripherally lap adjacent yarn packages.

3. A holder for multiple annular yarn packages or the like characterized as in claim 1, wherein each separator has oppositely-extending hub portions for engaging part way into the hollows of adjacent yarn packages in the pile; and wherein the inward groove-engaging lug is formed on one of said hub portions.

4. A holder for multiple annular yarn pack- 4 ages or the like characterized as in claim 1, wherein each separator has oppositely-extending hub portions for engaging part way into the hollows of adjacent yarn packages in the pile; wherein the inward groove-engaging lug is formed on one of said hub portions; wherein the stop element has a hub portion to engage upwardly into the hollow of the lowermost yarn package in the pile, and a circumferential flange to peripherally lap said package; and further including a discoid element similar to the separators for super-imposition upon the topmost package of the pile having a hub portion to engage into the hollow of the last mentioned package.

5. The invention defined in claim 1, wherein each .of the separators is formed by two components fashioned from sheet material and weldintegrated back to back, said components being formed respectively with hub portions for engaging into the hollows of adjacent packages in the pile; and wherein the stop and cover elements are each identical with one of the components of a separator.

- 6. A support for multiple annular yarn packages and the like characterized as in claim 1, wherein each separator is formed by two components fashioned from sheet metal and weldintegrated back to back, said components being formed respectively with hub portions for engaging into the hollows of adjacent packages in the pile; wherein the stop and cover elements are each identical with one of the components of a separator; wherein the hub portions of the separator components and of the stop and the cover elements are respectively provided with annularly arranged holes; and wherein the post is tubular and provided with plural rings of circumferentially arranged perforations centered in the mid transverse planes of the mountedpackages, and with other circumferentially arranged perforations ,in the transverse planes of the holes in the hub portions respectively of the separators, the stop element and the cover element.
